[0041] The seat back 62 of this embodiment is hinged to the seat board 61. After the seat board 61 is folded, the seat back 62 is manually folded toward the seat board 61, which is beneficial to reducing the folding area of the whole vehicle and further reducing the floor area. The setting of the seat back 62 provides backrest support for users and improves comfort.

[0042] As a preferred embodiment, it further includes a telescopic headstock assembly 70 and a gas spring 73. The front wheel assembly 10 is provided with a support seat 12. The headstock assembly 70 includes a headstock lower rod 71 and a headstock upper rod 72 telescopically arranged with the headstock lower rod 71. The lower end of the headstock lower rod 71 is hinged to the support seat 12. A fixing member 74 is arranged outside the headstock lower rod 71. The fixing member 74 is hinged with a connecting frame 75. The lower end of the gas spring 73 is hinged to the support seat 12. The telescopic end of the gas spring 73 is connected to the connecting frame 75. An adjusting wrench 76 is arranged at the upper end of the gas spring 73. The adjusting wrench 76 is connected to the upper end valve core switch of the gas spring 73, and the adjusting wrench 76 is hinged to the connecting frame 75. The telescoping of the gas spring 73 is controlled by the adjusting wrench 76.

[0043] In this embodiment, by setting the telescopic headstock assembly 70, the height of the headstock assembly 70 can be adjusted according to the actual needs of the user to ensure the comfort of using the scooter. The headstock assembly 70 is hinged to the front wheel assembly 10, and the angle between the headstock assembly 70 and the seat assembly 60 can be adjusted according to actual needs to ensure the comfort of using the scooter. After the headstock assembly 70 is adjusted by a certain angle, the gas spring 73 is used to lock the angle of the headstock assembly 70 to ensure the stability of the headstock assembly 70, further enhancing the stability of the whole scooter during use and ensuring the safety of using the scooter. Among them, the structure and working principle of the gas spring 73 are well known to those of ordinary skill in the art and will not be described in detail here.

[0044] Specifically, a control box 90 is provided at the upper end of the front rod 72 of the vehicle head, and vehicle handlebars 91 are arranged on both sides of the control box 90. The control box 90 includes a folding switch 92 for controlling the telescopic movement of the electric push rod 50. By operating the folding switch 92, the folding or unfolding of the mobility scooter can be achieved with one key, and the operation is simple and convenient. In addition, the mobility scooter further includes a motor assembly 80 for driving the rear wheel assembly 20 to rotate, and the motor assembly 80 is installed on the rear wheel assembly 20.

[0045] The structure and working principle of the electric push rod 50 involved in this electric folding mobility scooter are well-known to those of ordinary skill in the art, and will not be described in detail here.

[0046] In summary, the embodiment of the present invention provides an electric folding mobility scooter, which has at least the following beneficial effects: when the electric folding mobility scooter needs to be folded, the electric push rod 50 is started, and the extending end 51 of the electric push rod 50 pushes the rear end of the front frame 30 upward. Since the front end of the rear frame 40 is hinged to the rear end of the front frame 30 through the rear connecting rod 2, the front end of the front connecting rod 1 is hinged to the front wheel assembly 10, the rear end of the front connecting rod 1 is hinged to the front end of the rear connecting rod 2, the lower end of the seat linkage rod 6 is hinged to the rear end of the front frame 30, the upper end of the seat linkage rod 6 is hinged to the rear end of the seat assembly 60, the seat linkage rod 6 and the inclined support rod 41 are arranged crosswise and pivotally connected to each other in the middle. Therefore, when the extending end 51 of the electric push rod 50 extends, it can drive the rear end of the front frame 30 upward, and the front frame 30 drives the rear frame 40 to move upward at the same time. At the same time, the front connecting rod 1 drives the front wheel assembly 10 to move toward the direction close to the rear wheel assembly 20, assisting the front frame 30 and the rear frame 40 to be completely folded together. The front frame 30 also drives the lower end of the seat linkage rod 6 upward at the same time, and the lower end of the seat linkage rod 6 drives the seat assembly 60 downward. In this way, each part of the mobility scooter can be fully folded, ensuring that the volume of the mobility scooter is minimized, which is convenient for carrying and transportation. Moreover, the entire folding process is realized by the electric push rod 50, without consuming human power, and the operation is simple and convenient to use. When the mobility scooter needs to be opened, the electric push rod 50 is started again, the extending end 51 of the electric push rod 50 retracts, driving the front frame 30 to move downward, the front frame 30 drives the rear frame 40 to move downward at the same time, the front connecting rod 1 drives the front wheel assembly 10 to move toward the direction away from the rear wheel assembly 20, the front frame 30 also drives the lower end of the seat linkage rod 6 downward at the same time, and the lower end of the seat linkage rod 6 drives the seat assembly 60 upward. In this way, the mobility scooter can be opened, and the operation is very simple and convenient.
